Motivation For Starvation: Understanding The Neurobiology Of Anorexia Nervosa

Funding Amount

Summary
Anorexia nervosa is a debilitating psychiatric disorder which is currently untreatable. It is characterised by disrupted reward and cognitive processing. This project, which will ultimately inform treatment strategies, utilises the activity-based anorexia rat model combined with innovative behavioural paradigms and sophisticated techniques to manipulate and record from neural circuits. This will furnish a comprehensive understanding of the neurobiology involved in pathological weight loss.
Characterising The Muscarinic Receptor Deficit In Schizophrenia

Funding Amount

Summary
Post-mortem examination of the brains of schizophrenia patients reveals a substantial loss of muscarinic receptors. This is likely to be clinically very important if it can also be confirmed in living patients. Having developed a new scanning technique that shows muscarinic receptors in the living brain, we will now scan patients with schizophrenia to see if they also show this receptor loss, and see how it affects them. This could open new doors to understanding and treating the disease.
Using A National Level Multi-registry Analysis To Determine Whether Prescribed Anti-platelet Therapies Post-stroke Can Modify The Risk Of Cognitive Decline Or Dementia

Summary
Stroke survivors are at risk of dementia. Blood brain barrier damage after stroke may allow drugs in the bloodstream, which can be toxic to brain cells, to enter the brain. Clopidogrel, a drug commonly used after stroke, blocks a receptor essential for brain repair. After stroke, clopidogrel may access the brain and compromise repair processes, increasing the risk of dementia. We will link use of clopidogrel to the risk of dementia after stroke, using national Swedish health registry data.
Intergenerational Impacts Of Paternal Immune Activation On Brain Function And Dysfunction

Summary
We recently discovered that infection of male mice with a parasite (Toxoplasma gondii) before conception can change the epigenetic information in the sperm and alter behaviour of the offspring. This is the first evidence that pathogenic infection in males can affect the next generation. We will investigate how infection with other major pathogens, including bacteria and the virus causing COVID-19, may affect sperm epigenetics and offspring health, including their brain function and dysfunction.
Understanding Sex Differences In Alcohol Use Disorder: The Role Of Stress And Neuropeptides

Funding Amount
$692,106.00
Summary
Alcohol use disorders (AUD) are an emerging issue in women, yet there is little understanding of the how the male and female brains differ in response to excessive alcohol consumption. In pilot studies, we have found that deletion of a specific brain chemical causes differences in the way male and female mice consume alcohol in excess. We will further characterise this system and test new approaches to reduce the desire to consume alcohol.
ARX- A Hub Gene For A Common Biological Pathway In Schizophrenia

Funding Amount
$707,974.00
Summary
Schizophrenia is a severe psychiatric disorder with no cure. I have identified that some people with schizophrenia show variations to a gene called ARX. This project will use preclinical mouse models to explore how variations to the Arx gene affect brain molecules, networks of cells and behavioural outcomes. This biological pathway will provide the framework for the identification of new molecules to target therapeutically to modify the biological course of schizophrenia and improve outcomes.
